With the continuous development of the Internet, more and more websites need to conduct real-time statistics on their visits. As a scripting language widely used in web development, PHP can realize the function of real-time traffic statistics. This article will introduce the principles and steps of implementing PHP real-time traffic statistics technology.

Principle of real-time traffic statistics

The principle of real-time traffic statistics is to record each visit to the website and calculate the traffic in real time. Implementing this function requires the use of PHP's counter technology and background real-time statistics technology.

Counter technology: Counter technology refers to recording visits to a specific file or database by embedding counter code in the page. Generally, the information that the counter needs to record includes the total number of visits to the website, the number of daily visits, the number of visits per hour, etc.

Background real-time statistics technology: Background real-time statistics technology refers to the real-time statistics and analysis of data recorded by the counter through the background program. This technology can reflect website visits in real time, including traffic, geographical distribution, visitor sources, browser types, etc.

Steps for PHP to implement real-time traffic statistics

PHP to implement real-time traffic statistics generally includes the following steps:

1. Create a counter file or database table: counter file Or a database table to record the number of visits to each page. It can be created using PHP's file operation functions or database operation language.

2. Write counter code: Counter code is the core code for realizing visit statistics. Code is embedded into each page to accumulate page views. For example, you can add the following code to the page:

//Get the current page URL
$page_url = $_SERVER['REQUEST_URI'];

//Get the counter file
$counter_file = 'counter.txt';

//Open the file lock
$fp = fopen($counter_file, 'a ');
flock ($fp, LOCK_EX);

//Read counter
$counter_content = file_get_contents($counter_file);

//Increase page views by 1
$counter = isset($_SESSION['counter']) ? $_SESSION['counter'] : 0;
$counter ;
$_SESSION['counter'] = $counter;

//Will Visits are written to the counter file
$now_time = date('Y-m-d H:i:s');
$counter_content = str_replace($page_url, "$page_url,$counter,$now_time", $counter_content);
file_put_contents($counter_file, $counter_content);

//Release file lock
fflush($fp);
flock($fp, LOCK_UN);
fclose($fp );

In the above code, we first get the URL of the current page and get the counter file. We then wait for the other process by opening the file lock, reading the counter file, incrementing the page access count by 1, writing the access count to the counter file, and releasing the file lock.

3. Write the background real-time statistics code: The background real-time statistics code is used to conduct real-time statistics on the number of visits recorded in the counter file or database table, and analyze various statistical information. For example, you can write the following code:

//Get the counter file
$counter_file = 'counter.txt';

//Read Counter
$counter_content = file_get_contents($counter_file);

//Sort according to the number of visits
$counter_lines = explode("
", $counter_content);
rsort($ counter_lines);

//Output visit rankings
echo '

< ;th>Access time';
foreach($counter_lines as $line) {
if(trim($line) === '') continue;
list($url, $counter, $time) = explode(',', $line);
echo "";
}

//Output traffic statistics
echo "Total visits ".count($counter_lines)." pages.";
?>

In the above code, we first read the counter file, then sort by the number of visits, and output the visit ranking list , then count the number of pages visited, and output traffic statistics.

4. Apply statistics code: Finally, we need to apply the written counter code and background real-time statistics code to our website. Specifically, we need to embed the counter code in each page and include the background real-time statistics code in the background program.

Summary

PHP real-time traffic statistics technology is one of the commonly used technologies to achieve website traffic statistics. It uses counter technology and background real-time statistics technology to achieve real-time statistics and analysis of website visits. This article introduces the principles and steps of implementing real-time traffic statistics in PHP, hoping to provide some practical reference for web developers.
